"How did you feel about your first class?" On the way to the library, Gu Mengxue asked with a smile.

"It feels okay! Finally calmed them down before they could react, and overall, the first lesson was pretty good! Junxin said with a hint of a smile on the corner of his mouth.

"And did they accept you, a teacher who was even younger than them?"

"I don't know, but in my eyes, I'm afraid it's a little more likely to be accepted than to be rejected!" This sentence Junxin is not boasting, in the beginning of this lesson, he focused on some views on the use of mathematics in other disciplines, which belongs to the kind of very dry things, maybe for the average university, a little too esoteric and mysterious, but for the students of these top universities, it is a very useful thing. So they did accept the faith of the king much more than they rejected him.

"I'd like to go to your class too, but I've been busy lately and can't go!" Gu Mengxue said with a little regret. In fact, both Gu Mengxue and Junxin know that after they return to China and graduate in the future, there is a chance that they will stay in school to teach last. Teaching means that they will be looking at the classroom from the teacher's point of view, so if they have this kind of practical experience before, it will be of great help to themselves. And this public elective program provided by Princeton to Junxin has undoubtedly helped Junxin.

"Now that the course is on track, what's next?" Gu Mengxue, who didn't want to continue the topic, asked.

"Well, it may take a while to settle down next." After thinking about it, Junxin said decisively, "After all, we are still students, and there are many things to learn. For example, when I give a lecture now, I have already done self-study during the winter vacation, but it is better to listen to the professors' lectures. It is also an accumulation of knowledge. ”

"The other is the translation of mathematics books, after so many days of busy translation and sorting, the book initially named "Practical Mathematics Handbook" has completed one-tenth of its content, and now the course is on the right track, it is estimated that it will take less than two months to basically complete."

"Anything else?"

"Well, and when I was discussing with Professor Witten recently, Professor Witten suggested that I write a book on the development of superstring theory, and Professor John Schwartz also had the same idea, and I might be going to visit Professor Schwartz at the University of Southern California in a few days. Why don't you come with me? Junxin proposed.

"Where is USC?" Gu Mengxue asked with a frown.

"USC is in Los Angeles, and there's a more famous university, the University of California, Los Angeles. In the past, I always accidentally confused these two universities, thinking that they were the same university, only to find out later that the two universities are completely different. Junxin shook his head and said, "Okay, it's a bit far." Let's just say that there is something interesting in Los Angeles, well, in fact, there is nothing, but the Hollywood of the world film factory is in Los Angeles, don't you want to go and see it? ”

"When?" Gu Mengxue asked dryly.

"In a week!" Jun Xin said a little uncertainly, "I want to take this opportunity to go to Berkeley, it just so happens that Professor Chern is also there, and I will visit his old man by the way!" ”

"Okay, there's no problem on my side!" Gu Mengxue replied dryly.

"Oh, by the way, recently the school gave me a biology lab because of my curriculum to speed up my understanding of biology. Maybe when the course is stable, I'll have to spend a lot of time managing the lab! As if he remembered something, Junxin said in a slightly helpless tone.

"Your time is really..., since I met you, you said you weren't busy to death any day? Get up before dawn every day, and go to bed at eleven or twelve o'clock at night is commonplace, and now is not the time for thousands of troops to cross the single-plank bridge in the college entrance examination, do you need to fight so hard? Be careful with your own body! Gu Mengxue couldn't help but say. If she hadn't embarked on the path of academic research, she might not have been able to understand Jun's thoughts at all. In fact, even if she is now a like-minded person of Junxin, she can barely understand Junxin's paranoid pursuit of scientific research, but when it comes to the end, it is often indispensable to complain about Junxin.

"Alright, I got it!" Junxin didn't refute either, and said in a flat and somewhat doting tone.

"Forget it, let's talk about your lab!" Gu Mengxue no longer admonished, but instead asked about the laboratory tacitly.

"The laboratory was left by Professor Andrei Ivanov, who was a Soviet man during World War II and later settled in the United States, a well-known biologist in the industry, mainly engaged in stem cell research, and recently at the invitation of the Harvard School of Life Sciences, he resigned from the professorship at Princeton University to serve as a professor at Harvard University, and independently control a laboratory."

Speaking of this, Jun Xin couldn't help but complain: "To be honest, if you want to talk about theoretical disciplines such as physics and mathematics, it is obvious that Princeton is a little stronger, after all, it is backed by theoretical research institutions such as the Institute for Advanced Study in Princeton, but in applied disciplines such as biology and chemistry, Princeton is still not as good as a school like Harvard University!" Otherwise, Professor Ivanov would not have left Princeton. ”

"Is the lab fully equipped and stuffy?" As Junxin's assistant during the research of quasi-crystal experiments, Gu Mengxue was still relatively proficient in the construction of the laboratory, so he asked directly.

"First of all, Professor Ivanov's arrangement and management of the laboratory are very good, and the entire experimental platform is now running very well, even if he is gone, everything in the laboratory is still normal."

"Second, because I only use this laboratory for a short time, all the instruments and equipment, reagent consumables, and experimental personnel in it are quite complete, and I don't need to worry about anything at all, so everything is fine."

"Oh? So why do you spend so much time in the lab, you ask? Gu Mengxue said.

"About this, the main reason is that I have seen too much biological data recently, and I always have some ideas in my heart, and I want to design some experiments to verify them!" Junxin said with a satisfied smile on his face.
